After using a phone like OPPO Find N3 512GB, various issues may arise, and the situation of a swollen phone battery is highly perilous. Users should promptly seek solutions to rectify this issue.

A swollen phone battery poses a life-threatening risk if continued to be used.
1. Causes of a swollen phone battery
The phenomenon of a swollen phone battery can arise from common causes such as:
- Excessive charging current leading the battery to consistently maintain a temperature of 35 degrees Celsius (equivalent to 95 degrees Fahrenheit). The multiple layers covering the phone battery or charging during hot summer weather can trap high temperatures, potentially causing damage or swelling during use.
- Users often have the habit of using the phone until the battery drops below 10% or even shuts down. This situation triggers chemical reactions, causing a gradual decrease in energy within the battery. Prolonged instances can result in the battery becoming deformed or swollen, leading to a reduced lifespan.
- Utilizing low-quality batteries or chargers.
- Users often engage in simultaneous charging and phone usage.
- Continuing to charge when the battery capacity has already reached the maximum of 100%.
- The phone frequently experiences falls, drops in water, screen breakages, and water seeping into the interior.

The habit of using the phone while charging is one of the factors leading to phone battery swelling.
2. Signs of a Swollen Battery
You can identify a swollen battery through various signs or harmful charging habits, ranging from mild to severe. Specifically:
- The phone screen may slightly lift, creating discomfort during use.
- The phone quickly drains its battery even after a relatively short time of being fully charged.
- The phone tends to heat up or shut down abruptly during usage.
3. Is it dangerous if the phone battery is swollen?
The swollen condition of a phone battery poses a significant risk to users. At this point, the battery life decreases, and maintaining a high level of heat can lead to the release of a mixture of electrolytic gases. This can result in explosion or fire while using a phone with a swollen battery.
Additionally, a swollen battery creates a gap between the body and the phone screen, which can lead to electric shocks during charging. Therefore, if you're wondering whether you can charge a swollen battery, the answer is 'no'. You should avoid charging the battery and stop using the phone to ensure safety.

4. Remedies for a Swollen Phone Battery
Upon discovering a phone with a swollen battery, you can address the issue using the following methods:
- Avoid charging and cease using the phone
As soon as you notice the phone battery swelling, disconnect from any power source, and preferably, turn off the phone immediately.
- Find a way to remove the phone battery
If your mobile phone uses a removable battery, turn off the phone and carefully remove the battery to prevent the release of gases. Then, place the battery in a high, out-of-reach location, away from the reach of small children.
- Dispose of the phone battery safely and properly
Batteries are hazardous waste that cannot decompose naturally, so make sure to take them to designated collection points in your local area. Avoid disposing of batteries with household waste, as it can pose dangers and contribute to environmental pollution.
- Replace the phone battery with a new one
Take your phone to reputable service centers for a proper check-up and battery replacement. Additionally, ensure that you replace it with an authentic battery for efficient and safer usage.

It's advisable to take your phone to a repair center for inspection and replacement with a genuine new battery.

5. Tips to Prevent Phone Battery Swelling
To minimize the risk of battery swelling, keep in mind a few tips while using your phone, such as:

- Unplug the charger immediately when the phone indicates a 100% battery charge.
- Avoid charging while the phone is hot from gaming, watching movies, etc., as charging time will be longer than usual, leading to increased battery and device temperatures.
- Charge your phone in a well-ventilated environment, and avoid placing it on a pillow, as it can generate high heat concentration, posing a risk of explosion.

Charge your phone in a well-ventilated environment, and never place it on a bed or blanket.
